In the PCB copying industry, the cost of drilling holes in PCB boards is usually 30% to 40% of the cost of PCB board manufacturing, and vias are one of the important components of multilayer PCBs. In short, every hole on a PCB can be called a via. Vias appear as discontinuous impedance breakpoints on…
Although the current EDA tools are very powerful, as the PCB size requirements are getting smaller and smaller and the device density is getting higher and higher, the difficulty of PCB design is not small. How to achieve a high PCB routing rate and shorten the design time? This article introduces the design skills and…
Optoelectronic printed circuit boards use high-speed optical connection technology to replace the copper wire connection currently used in computers, using photons instead of electrons as the medium to transmit data between circuit boards, chips and even various parts of chips. At the same time, traditional low-efficiency electrical signals can also be transmitted. Its basic working…

The three-coordinate measuring machine is a new type of high-efficiency precision measuring instrument that has been widely used in the fields of mechanical manufacturing, electronics, automobiles, and aerospace in the past three decades. It can detect the size, shape, and relative position of the workpiece, and complete the measurement of the spatial profiles of the…
Traditional tools for debugging PCB include: time domain oscilloscope, TDR (time domain reflectometry) oscilloscope, logic analyzer, and frequency domain spectrum analyzer, but these means cannot provide data reflecting the overall information of PCB board. PCB board is also called printed circuit board, printed wiring board, or printed board for short, PCB (printed circuit board) or…
The global energy shortage problem has led governments around the world to vigorously promote new energy-saving policies. The energy consumption standards for electronic products are becoming increasingly stringent. For power design engineers, how to design more efficient and high-performance power supplies is an eternal challenge. Starting from the layout of the power supply PCB, this…
“Explore reverse engineering techniques for vintage Microtek PCBs, analyzing 1980s circuit design architecture and component-level functionality in embedded systems.”
1.Definition of ground What is ground? The definition of ground that everyone learns in textbooks is: ground is an equipotential body that serves as the potential reference point of the circuit. This definition does not conform to the actual situation. The potential on the actual ground is not constant. If you use an instrument to…
With the development of science and technology, the market demand for electronic components is increasing. In order to improve the soldering quality of electronic components, manufacturers have replaced traditional manual soldering with automatic soldering machines to increase production. As production increases, various problems follow. With years of experience in solving soldering problems, the technical staff…
How to reduce the mutual interference between digital signals and analog signals? Before designing, we must understand the two basic principles of electromagnetic compatibility (EMC): the first principle is to reduce the area of the current loop as much as possible; the second principle is that the system uses only one reference plane. On the…
R&D personnel consider how to integrate the latest advanced technologies into products. These advanced technologies can be reflected in both excellent product functions and reduced product costs. The challenge is how to effectively apply these technologies to products. There are many factors to consider, and the time to market is one of the most important…
At present, there are four main new generation cleaning technologies for circuit boards: 1.Semi-aqueous cleaning technology Semi-aqueous cleaning mainly uses organic solvents and deionized water, plus a certain amount of surfactants and additives to form a cleaning agent. This type of cleaning is between solvent cleaning and water cleaning. These cleaning agents are all organic…
Tin wire is one of the welding materials for electronic products, and tin wire is divided into lead tin wire and lead-free tin wire. The price of lead-free tin wire is much higher than that of lead tin wire, which will greatly increase the cost of welding materials. Why should automatic soldering machine merchants choose…
